Referring now particularly to FIGS. 1, 2 and 3, it will be observed that the reference character 10 designates, generally, a railway car axle having an axle journal 11 provided with an end collar 12. The axis of rotation of the axle 10 is indicated at 14. The axle 10 projects into a railway car journal box that is indicated, generally, at 14 and includes a top 15, a curved bottom 16 and vertical side walls 17 and 18. Overlying the axle journal 11 is a journal bearing 19 which has a wedge 20 interposed between it and the underside of the top 15. Stop columns 21 and 22 on the side walls 17 and 18 limit the relative horizontal movement of the wedge 20 and journal bearing 19 with respect to the side walls 17 and 18 of the journal box 14.

With a view to limiting relative horizontal movement between the axle 10 and the side walls 17 and 18 caused by acceleration or deceleration of the car and application of the brakes, means are provided for limiting such movement in the form of journal guide means mounted on the respective side walls 17 and 18.

The journal guide means include journal guide supports that are indicated, generally, at 23 which are of duplicate construction the details of which are shown in FIGS. 4, 5, 6 and 7. Here it will be observed that the journal guide support 23 is generally U-shaped. It is formed of pressed steel which can be blanked out and formed to the configuration shown. The journal guide support 23 is arranged to be Welded, as indicated at 24 in FIGS. 1, 2 and 3, to the side walls 17 and 18.

The journal guide support 23 includes a bottom 25 having a rear side 26 extending upwardly therefrom. The rear side 26 has a notch 27 to clear the respective stop column 21 or 22. The rear side 26 also includes bifurcated end sections indicated generally at 28 and 29 which are arranged to lie flat against the inner sides of the vertical side walls 17 and 18. It is desirable that means he provided for mounting journal stops or guides to be described on the journal guide support 23. For this purpose T-members 30 and 31 are provided as integral parts of the journal guide support 23. Each of the T-members 30 and 31 includes an upper section 32 that is formed from the rear side 26 and particularly from that portion between the furcations of the end sections 28 and 29. Each T- rnember 30 and 31 also includes a lower section 33 which forms a part of the front side of the journal guide sup.- port 23 with the sections 32 and 33 being deformed, as shown in FIG. 7, with key entrance portions 34 and 35 on opposite sides for receiving a key, to be described, from either side depending upon whether the journal guide support 23 is mounted on the side wall 17 or '18. The front side of the journal guide support 23 also includes an intermediate front side section 36 having key entrance portions 37 at its ends. The construction of the journal guide support 23 is such as to provide a key receiving groove 38 from end to end that is generally rectangular in cross section. A key engaging bottom surface 39 is provided on the rear sides of the upper and lower sections 32 and 33 of each of the T-members 30 and 31. Also a key engaging bottom surface 40 is provided on the rear side of the intermediate front side section 36. It will be observed that the key engaging bottom surfaces 39 and 40 face the side wall 17 or 18, depending upon the location of the respective journal guide support 23.

It will be understood that a journal guide support 23 is positioned, as shown in FIG. 1, on each of the vertical side walls 17 and 18 prior to the insertion of the axle journal 11 into the journal box 14. The journal guide supports 23 are held in the proper positions by suitable jigs which are arranged and constructed to facilitate the welding operations indicated at 24.

Detachably mounted on each journal guide support 23 are two journal stops or guides indicated, generally, at 44 and 45. FIGS. 8 to 12 show the details of construction of the journal stop or guide 44, it being understood that the journal stop or guide 45 is a duplicate of this construction.

FIGS. 8 and 9 show the backing portion, indicated at 46, for use in forming the complete journal stop or guide 44. Preferably the backing portion 46 is formed of malleable iron.

With a view to detachably mounting the backing portion 46 on one or the other of the T-members 30 or 31, each backing portion 46 is provided or formed with T-slot means that is indicated, generally, at 47. In part each T-slot means 47 is defined by shoulders 48 that are arranged, as shown in FIG. 9, to engage the juxtaposed surface of the respective T-member 30 when the backing portion 46 is applied from a location above the respective journal guide support 23. FIG. 9 shows one of the T- members 30 in broken outline in the preliminary positioning of the journal stop or guide 44. As shown more clearly in FIGS. 11 and 12 each backing portion 46 has a key receiving groove 49 that extends transversely of the respective T-slot means 47. The key receiving groove 49 is defined, in part, by inclined key engaging bottom surfaces 50 that are arranged, as shown in FIG. 2, to face away from the respective side wall 17 or 18. On the front side of each backing portion 46 there is a central boss 51 at the ends of which there are top and bottom flanges 52. Side flanges 53 and 54 are formed integral along the opposite vertical sides of the central boss 51 and are arranged, as shown in FIG. 12, to be deformed over side flanges 54 of a bearing portion 55 that is formed of a material, such as forged bronze, that is relatively expensive as compared to the material, malleable iron, of which the backing portion 46 is formed. Each bearing portion 55 has a vertical bearing surface 56 that, as shown in FIG. 1, normally is spaced from the diametrically opposite sides of the axle journay 11. Each vertical bearing surface 56 is arranged to be engaged by and to limit the movement of the axle journal 11, depending upon its relative movement with respect to the journal box 14.

Initially the journal stops or guides 44 and 45 are applied to the Trnembers 30 and 31 by inserting them from above the journal guide support 23. In each case the T- slot means 47 loosely interfits with the T-member 30 or 31 so that the journal stops or guides 44 and 45 are held in a preliminary manner. This is illustrated in FIG. 2 with respect to the journal stop or guide 45. Here it will be observed that a slight space 57 exists between the juxtaposed surface of the rear side 26 and the rear surface of the backing portion 46. In this position, as pointed out above, the shoulders 48 extending along the T-slot means 47 engage the juxtaposed side surfaces of the T-member 31.

In order to hold securely each of the journal stops or guides 44 and 45 in position on the journal guide support 23, key means 59 are provided, one for each journal guide support 23. The key means 59 preferably is formed of spring steel and has a rectangular cross section as shown in FIG. 1. It is somewhat flexible and has a beveled and curved end 60 to facilitate its application. At the other end there is a handle section 61 which is provided with a slot 62 for receiving a tool to assist in application or re moval of the key means 59. Adjacent the handle section 61 there is a deformed key lock section 63 that is arranged, as shown in FIG. 2, to engage one of the inclined key engaging bottom surfaces 50 to prevent accidental endwise movement of the respective key means 59.

In operation, after the journal guide supports 23 have been welded to the inner sides of the vertical side walls 17 and 18 of the journal box 14, the axle 10 is inserted to position the axle journal 11 therein. Then the journal stops or guides 44 and 45 are applied to the journal guide supports 23 on opposite sides of the axle journal 11 by aligning the respective T-slot means 47 with the T-members 30 and 31 and permitting them to move downwardly until they engage the bottom 25. The journal stops or guides 44 and 45 then are in preliminary positions as illustrated in the lower right corner of FIG. 2. Finally the key means 59 is inserted, the beveled and curved end 60 being first applied to the outer end of the key receiving groove 49 in the journal stop or guide 44 and moved inwardly until the key entrance portion 35 is engaged. The continued inward movement of the key means 59 engages the bottom surface 39 on the T-member 3t) and reacts against it and the key engaging bottom surfaces 50 of the backing portion 46 to move the journal stop or guide 44 to the final operative position. The continued movement of the key means 59 causes the beveled and curved end 60 to engage the entrance portion 37 of the intermediate front side section 36 and then to move along the bottom surface 40 thereof. This action is repeated with respect to the journal stop or guide 45 so that finally it is moved to the operative position as shown in the upper part of FIG. 2. In the fully inserted position the key means 59 is located with the deformed key lock section 63 in engagement with one of the inclined key engaging bottom surfaces 50 of the journal stop or guide 44. In order to withdraw the key means 59 it is necessary to deflect the handle section 60 away from the vertical side wall 17 or 18 and then to apply a tension force to the slot 62 by a suitable tool.

After the journal stops or guides 44 and 45 have been locked in operative positions on opposite sides of the axle journal 11, the journal bearing 19 and the wedge 20 are inserted. When the journal stops or guides 44 and 45 are to be removed, the foregoing sequence of operations is reversed. After the key means 59 are withdrawn, the journal stops or guides 44 and 45 can be removed by lifting them from the T-members 30 and 31. I

In FIG. 2 it will be noted that the rear surfaces of the backing portions 46 of the journal stops or guides 44 and 45 bear directly against the inner surfaces of the rear sides 26 of the journal guide supports 23 which, in turn, are juxtaposed to the inner surfaces of the vertical side walls 17 and 18 of the journal box 14. The forces applied to the bearing surfaces 56 of the bearing portions 55 by the axle journal 11 are transmitted directly through the journal stops or guides 44 and 45 to the respective side walls 17 and 18.

Another embodiment of the invention is shown in FIGS. 13 to 20. Here the journal stop construction and mounting therefor serve to limit the horizontal movement of the axle journal 11 with respect to the journal box 14 in the manner described hereinbefore with reference to FIGS. 1 to 12. However, the construction and mounting for the journal stops or guides are different.

As shown in FIGS. 14 to 17 a journal guide support is illustrated, generally, at 66 and, as shown in FIG. 13, is arranged to be mounted on the inner side of each of the vertical side walls 17 and 18 of the journal box 14. Each journal guide support 66 is generally channel shaped and is formed of mild steel. The journal guide support 66 includes a web 67 having a top flange 68 and a bottom flange 69 that are arranged, as shown in FIG. 13, to bear against the inner side of the vertical side walls 17 and 18. They are arranged to be welded thereto as indicated at 70. A notch 71 is provided in the top flange 68 in order to clear the respective stop column 21 or 22.

For mounting journal stops or guides, to be described, there are provided T-slot means 72 and 73 near the ends of the journal g-uide support 66 and in the web 67 and the top flange 68. Each journal guide support 66 provides a key receiving groove 74 having key engaging bottom surfaces 75 at the ends and a key engaging bottom surface 76 at the central portion thereof, these key engaging surfaces facing the inner sides of the vertical side walls 17 and 18. These key engaging surfaces 75 and 76 are curved, as shown in FIGS. 13 and 15, in order to direct the key means 59, previously described, along the key receiving groove 74.

For limiting the horizontal movement of the axle journal 11 with respect to the journal box 14 journal stops or guides, shown generally at 80 and 81 in FIG. 13, are provided. It will be noted that the two journal stops 80 and 81 are mounted at the ends of the journal guide supports 66 and that they are duplicates of each other. The details of construction are shown in FIGS. 18, 19 and 20. Each journal guide or stop includes a backing portion 82 preferably formed, of malleable iron and having an integral T-member shown generally at 83 which includes a stem 84 and a head 85. The T-member 83 on each of the journal stops 80 and 81 is arranged to interfit with the T-slot means 72 and 73.

When one of the journal stops or guides, such as the stop or guide 80 is applied in a preliminary manner, shoulders 86 at the inner side of the T-member engage the Web 67 at the sides of the T-slot means 72. Thus the journal stops or guides 80 and 81 are temporarily held in position on the journal guide support 66 as the result of the interfitting relationship between the T-slot means 72 and 73 and the T-member 83 on the respective journal stop or guide 80 or 81. A key receiving groove 87 extends transversely through each T-member 83 and it has a key engaging bottom surface 88 that faces away from the respective vertical side walls 17 or 18. Key entrance portions 89 are disposed at the lateral sides of the key engaging bottom surface 88 to facilitate entrance of the beveled and curved end 60 of the key means 59. On the opposite side of the backing portion 82 there are a central boss 92 and top and bottom flanges 93. Side flanges 94 extend from the front side of the backing portion 82 and, as shown in FIG. 20, are arranged to be deformed over side flanges 95 of a bearing portion 96 having a vertical bearing surface 97. The bearing portion 96 can be a duplicate of the bearing portion 55, previously described.

On initial application of the journal stops or guides 80 and 81 to the journal guide support 66, the T-member 83 of each loosely interfits with the respective T-slot means 72 or 73 as shown in the lower right portion of FIG. 13 so that a space 98 is provided between the rear surface of the backing portion 82 and the juxtaposed front surface of the web 67.

If desired, a recess 99 can be formed in the rear side of the boss 92 in order to reduce the amount of metal required.

Prior to insertion of the axle 10 into the journal box 14 the journal guide supports 66 are welded, as indicated at 70, to the inner sides of the vertical side. walls 17 and 18. Then the axle 10 is inserted into the journal box 14. Next the journal stops or guides and 81 are applied to the journal guide supports 66 by placing their T-members 83 in alignment with the T-slot means 72 and 73 in the respective journal guide support 66. Initially the journal stops or guides 80 and 81 loosely interfit with the journal guide support 66 with the space indicated at 98 in the lower right portion of FIG. 13 appearing with the journal stops or guides 80 and 81 positioned inwardly a corresponding distance from the side walls 17 and 18, Finally the key means 59 are inserted, the beveled and curved end 60 first being applied adjacent the outer key engaging bottom surface 75, and then on inward movement engaging the key entrance portion 89 of the journal stop or guide 80. Continued inward movement of the key means 59 causes the journal stop or guide 8 0 to be moved to the position shown in FIG. 13 while the continued inward movement of the key means 59 brings the end 60 into engagement with the key engaging bottom surface 76 on the web 67. The inward movement of the key means 59 continues until the entrance portion 89 on the journal stop or guide 81 is engaged to move it to the operative position followed by engagement of the inner key engaging bottom surface 76 and deflection of the end 60 of the key means 59 toward the respective side wall 17 or 18. The inward movement of the key means is arrested on engagement of the right end of the handle section 61 with the outer end of the journal guide support 66 in which position the deformed key lock section 63 is in locking engagement with the adjacent key engaging bottom surface 75.

When the journal stops or guides 80 and 81 are to be removed, the key means 59 are withdrawn and the foregoing application steps are reversed.

As pointed out in both embodiments of the invention bearing portions 55 and 96 are supported in backing portions 46 and 82. This construction makes it possible to employ a relatively small amount of the bearing material for the bearing portions 55 and 96 while the backing portions 46 and 82 are formed of relatively inexpensive material. However, if desired, the journal stops 44 and 45 and 80 and 81 can be formed entirely of bearing material, bronze for example.

Since adequate bearing area is provided by the two journal stops or guides 44 and 45 and 80 and 81, it is unnecessary to extend the bearing area for the entire length of the journal guide supports 23 or 66. However, it increased bearing area is desired, the bearing portions 55 and 96 can be extended into single bearing portions extending substantially the full length of the journal guide supports 23 and 66.
